## Discrepancy

AIRCRAFT LOST NR 4 RIGHT AFT MLG WHEEL.  RETURNED TO FIELD. WHEEL LOSS BELIEVED DUE TO BEARING FAILURE.  INSPECTION OF RECOVERED PARTS REFLECT LACK OF LUBRICATION OF INBOARD WHEEL BEARING.   NR 4R WHEEL AND BRAKE REPLACED.  NR 3R MATE REPLACED, REAR AXLE REPLACED.  EXTENSION-RETRACTION TEST ACCOMPLISHED CHECKED OKAY.
